Materials used in additive manufacturing should display a favorable balance of mechanical and rheological properties. Acrylonitrile-butadiene-styrene (ABS) terpolymer is one of the most commonly used plastics in Fused Deposition Modeling (FDM) due to its ease of processability. ABS by itself is considered to be at the lower end of the spectrum of engineering plastics due to its low impact resistance and toughness. Its mechanical and chemical properties can be enhanced through the use of fillers. However, currently the use of filler-reinforced thermoplastics is limited in 3D printing due to the poor weld strength of the printed materials. This study aims to investigate mechanical properties of printed parts made from pure ABS as well as ABS-nanoclay composites with a FDM 3D printer. Built in stresses of the printed parts will also be studied.
